## Summary description

VAREM expansion vessel model R1012228 with 12 L capacity, designed for DRI systems. This pressure vessel provides controlled thermal expansion compensation in closed heating or domestic water systems compatible with DRI components. Key features include a 12-litre nominal volume and suitability for maintaining system pressure and preventing overpressure during temperature changes.

## Long description

VAREM expansion vessel R1012228 with 12 L nominal capacity is designed for closed heating and domestic water systems that use DRI components. The vessel provides a flexible air cushion to accommodate thermal expansion of water, helping to maintain system pressure and reduce cycling of pumps and valves. Constructed to be fitted into installations where a compact, reliable expansion device is required, this unit supports the proper functioning of pressure regulation and overpressure prevention during temperature fluctuations.
Advantages
The vessel offers a 12-litre nominal volume in a compact body suitable for space-limited installations. Its design ensures stable pressure buffering and reduced stress on system components by absorbing sudden volume changes. The product is compatible with DRI system configurations and contributes to improved system longevity through consistent pressure control and prevention of frequent relief valve activation.
Suitable for
 Closed central heating systems incorporating DRI components
 Domestic hot water systems requiring thermal expansion compensation
 Small commercial installations where a 12 L expansion vessel is appropriate
 Retrofitting or replacing existing expansion vessels of similar capacity
Key specifications
 Nominal volume: 12 litres
 Application: closed heating and domestic water systems compatible with DRI components
 Function: thermal expansion compensation and pressure buffering
 Form factor: compact vessel for inline or cabinet-mounted installations
How to use
Install the expansion vessel according to the system layout, ensuring correct orientation and secure mechanical connection to the system pipework. Pre-charge the vessel to the manufacturer-recommended air pressure for the specific system static pressure before commissioning. After installation, check for leaks and verify system pressure behaviour during heating and cooling cycles, adjusting the pre-charge or isolation valves as required to achieve stable operation.
Usage recommendations
Perform periodic checks of the vessel pre-charge pressure and inspect connections for corrosion or leakage. When replacing an existing vessel, match the nominal volume and verify compatibility with the DRI configuration of the system. Follow national and local installation codes and the system manufacturer's guidance for safe operation and maintenance.
